Seven-year-old Ling Yun was a carefree child in Qingshi Village. A tragedy that destroyed the village broke the tranquility - the Witch God Sect was looking for the ancient treasure Hongmeng Pearl and bloodbathed the whole village. His adoptive parents died tragically to protect him. When he was about to die, Master Qingxuan of the Lingxiao Sect came to the rescue and revealed his shocking life experience as the orphan of Lingxiao Sword Immortal Ling Xiaotian and Nangong Wan, the legitimate daughter of the Nangong family.
Armed with the legendary talent of Chaos Spirit Root and carrying a mysterious jade pendant engraved with the word "cloud", Ling Yun joined the Lingxiao Sect and embarked on the road of cultivating immortality and revenge. He understood the meaning of the sword in the sword tomb, experienced life and death in the secret realm, learned the "Purple Sky Thunder Sound Sword" and "Chaos Evolution Technique", and his cultivation improved rapidly. However, the crisis is never far away: the Shadow Pavilion killer Mu Ying follows him like a shadow, the traitor in the Nangong family covets the inheritance, the Witch God Sect is pressing closer, and all forces come for the Hongmeng Orb and the secrets of the Nangong family.
In order to eliminate the shadow poison in the body, Ling Yun and his partners went deep into the Rotting Bone Swamp in southern Xinjiang. After experiencing the horror of phosphorus fire, the crocodile king blocking the road, and the shadow of the miasma, they successfully obtained the Qingying Glazed Flower, but accidentally triggered the ancient formation of the Nangong family, and got a glimpse of the deeper secrets of inheritance. As the mystery of his life experience is gradually revealed, the truth about his parents' murder, the whereabouts of the Hongmeng Orb, and the undercurrent of the world of immortality all push him into the center of the storm.
This is a journey of cultivating immortality with swords as the guide and hatred as the guide. Ling Yun must not only stick to his true heart in the confrontation between good and evil, but also protect his companions from multiple sieges, and also uncover the grudges spanning three generations. How to unlock the potential of Chaos Spirit Root? Can the secret of Hongmeng Orb be revealed? Let's watch the young man Ling Yun break the situation with his sword, achieve nirvana in the blood and fire, and find his own sword path in this world.
